Covertron® 600  

Flexible pretreatment process for plastic metallization

Covertron® 600 is our latest development in our range of Cr-free plastic pretreatment processes. The reliable process is able to deliver similar performance and quality as the current Cr(VI) benchmark. Compatible with immersion copper as well as nickel strike, it allows for a simple integration into the existing or new plating lines.

By eliminating the need for hexavalent chromium for the etching of plastics, Covertron® 600 fulfills REACH regulations. It is compatible with a large variety of polymers, including most of the currently plateable ABS or ABS/PC resins as well as selective plating. Covertron® 600 finally completes our range of sustainable processes for the future of electroplating of plastics.


What inspires us

Why we developed Covertron® 600

Your challenge

Chromium trioxide, a Substance of Very High Concern (SVHC) according to REACH, requires authorization for use of in Europe since September 21, 2017. With an interest extending far beyond Europe to eliminate hazardous chemicals, customers are looking for alternatives to hexavalent chromium containing processes which meet the current technical requirements of the industry for the pretreatment of plastics.

Our solution

Having been involved in plating on plastics since the very beginning, Atotech has long been committed to developing alternatives to chromosulfuric acid etching for the pretreatment of plastics and the task has not been easy. With Covertron® 600, our latest generation of Cr-free etching, we offer a robust process able to match the technical performance of the current chromosulfuric etching.
